High in the Dolomites of northeastern Italy, Italian researchers chipping away at rocks formed more than 200 million years ago found two miniscule mites and a fly preserved in tiny drops of amber. Highly-magnified photographs of the creatures show the mites, in particular, to be perfectly preserved. At 230 million years old, they're about 100 million years older than the oldest previous find of their kind.
The bugs probably fed off the leaves of the tree in whose resin they were eventually preserved. Researchers say the discovery shows the mites' ability to adapt to changing evolutionary conditions. For film lovers, though, it has striking echoes of the Steven Spielberg blockbuster, Jurassic Park, in which a team of scientists use the DNA of a mosquito preserved in amber to recreate dinosaurs with predictably terrifying results. |
